Web Crawler

Do web crawing to scrape website

If you are looking for a program that can pick out the information you need from anywhere on the Internet, then you need a web crawler. Web crawlers, also known as web spiders, are used in many search engines to find sites related to specific key words.

Search engines cannot exist and operate successfully without web crawlers because they are superb tools that make them to gather information about websites easily. This is another reason for which the details of their architecture and algorithms are often kept as business secrets. FMiner is a more advanced web crawler that works more efficiently and more powerfully than other programs.

What is a Web Crawler?

A web crawler does a systematic search of Internet sites to find pages that are applicable to the information that is needed. As with many current internet browsers, keywords are used to search for a specific term, phrase, or words. Web crawlers are so effective at searching for these terms that they perform the physical search used by common web browsers.

How a Web Crawler Works

Web browsers systematically send out web crawlers, or spiders, which then find websites and copy portions of the pages’ web address, hyperlinks and phrases. This information is then cataloged or indexed before it is stored. The process allows the program to quickly sift through the indexed data using the proper criteria without the need to search the entire Internet.

A specialized web crawler can catalog whole sites, or they can harvest only general information in order to label a site within a database. Initial web crawlers worked quickly because the information on the Internet was limited. In modern times, web crawlers are constantly searching new sites for data, links, views, and information as well as regularly rechecking existing sites for updated or changed information. Modern crawl programs are even used to find similar terms or to harvest contact information such as:
